if you have a spare key fob try batteries in other one to make sure batteries are not faulty even though they are new. If not it will be the micro chip in key fob so you need a new key. Timpsons Shoe and Key repairer,where i had to purchase a new key fob myself was far cheaper than main dealer which i payed 25 pounds for paul
